of K required for an allowable steady-state error of 2% P412 Two feedback systems are shown in Figures P4.12(a) and (b) (a) Evaluate the closed-loop transfer func tions 7, and T

for each system. (b) Compare the sensitivities of the two systems with respect to the parameter K for the nominal values of K₁ = K₁ = 1. FIGURE P4.12 Two feedback systems.
